ing end 11 of the arm 8 is so positioned as brake shoe in elevated position Sduring the rotation of the record, as will presently appear. I s n f Mounted longitudinally of and within the casing 6 andcapable of 'a longitudinal movement therein, is a plate 12, which by means of the screw and slot connection 12, 'isproperly secured to the casing and f has pivotally connected to the inner end there of a catch' 13, whose spring 14 normally holds the same downwardly and in'rigi'dconnection to provide a lock for the reduced end 11 of the brake shoe carrying arm `8 to hold under normal conditions, the brake shoe and arm in the elevated position as shown in Fig. 1

Connected to the forward end of the plate 12 within the casing 6, is a depending lug 15 which is carried by the arm 16, said,-

rMo'unted for l vertical, or longitudinal sliding movement withinl the Vfree end of the 1 "casing 6 is the:v 'stylus factuated releasing 90 mechanism 2 8' ofthe device, the same being `mounted' bymeans ofl the" slot and screw connection 28 -to the bottom of the casing 6 and having. onnectedto the rear portion y thereof, the arm or rod 29 upon the vedge of '95 30 are in engagementat :allvtii'n'es with-the teeth of the` gear 31 keyed upon and rotatable withthejvertical shaft 32 journal'ed i within the casing 6.V Upon the upper end 100 ofath'e yshaft 32.v is 'keyed-.a milled. ,disk33 which lis provided-,withythe dial numbers 34 which in conjunction'with the stationary pointer 35 carried by Athe casing 6, indicates at a glance, the consequent projection or retraction of the outer 'free end ofthe device 28, these numbers indicatingV the various` grooves within the record adjacent to the usual plain portion formed concentrically of the record, s o.that the rotation of the record may be halted at any desired point before the passage of the stylus S out of the y grooves upon such plain portion. f Mounted for transverseiswinging movement within the device 28 through the me- 1154 dium of the hinges 36-37 is the longitudi-- nal plate 38 which is disposed to, at all times when raised abut the lower end 27 of the vertical' rod 25 and thus move the braking disk 24 out of Vengagement with 120 the brake wheel or disk 23 of the retarding mechanism mountedin the easing' 22. This releasing bar or plate 38 is of such a length that a 'portion thereof will always' l be below the lower end 27 of the vertically 125 slid able releasing rod 25 so thatregardless of the position of the device 28 within the casing 6, the said releasing plate or-bar 38 will always be in operable relation to the same. The forward end 39 of the bar 38 is 13a positioned to be above the reduced bar act-uating lip or lug 40 of the bar actuating device 41, which is provided with the trans# lverse sleeve 42 journaled upon the pin 43 consequently the bar 38. This bar 38 will elevate the pin or rod 25 and thus release the gear escapement 22, releasing the arm 15 to the action of its spring, so that the plate 12 unlocks the brake shoe. This stops the record andthe record carrying platform of the machine.

In order to Visually indicate the position of the lever 1G,so that the operator will know when the brake shoe is properly set and out of engagement with the record R, the aperture 45 is provided in the casing l(3, while a target indicator 46 is carried'by the upper face of the arm 16, as clearly shown in Fig. 2.

In order to provide a means for resetting the plate 12 as the casing 6 is moved away from the record R, a segmental slot 47 is provided in one side of the supporting casing 6 near the pivoting pin 5 and has projected therethrough the pin 48 which is connected to one of the lugs or posts 4, said pin havingdisposed upon its inner end within the casing 6, the curvedlend 49 of the setting lever 50, whose forward end is slotted, as at 51, to engage the pin 52 connected to and carried bythe lug 15. It will thus be seen that when the parts have assumed the dotted lineV position in Fig. 1 and the casing 6 is raised from such position to the dotted line position in Fig. 3, that. the

setting lever 50, due to the said swinging movement from its stationary position relatively to the pin 48 will cause the arm 16 to be moved from the position as shown in full lines Fig. 3 to dotted line position` therein, the brake shoe carrying disk 7 being moved during this operation from the dotted line position, as shown in Fig. 1 to the full line position by means of the pin and slot 62, so that the reduced end 11 will be placed in engagementl with the trigger or lock 13, thus simultaneously resetting the brake shoe and the lever 16, which due to its pawl 2O will engage the teeth of the gear 21 and be locked in the position as shown in Fig. 2. Thus when the casing 16 is lowered above the record R, the brake shoe will be placed above and out of contactwith the record and Athe parts will be reset,

the indicator or target 46 indicating at a glance that the plate 12 is in the proper position for actuation by the stylus S.

By means of the cam edge 57 and depression 57 carried by one portion of the casing 6 near the pivotal point thereof, the roller 55 carried upon the spring 54 is at the proper time depressed and removed from engagement with t-he shouldered portion of the actuating lug 58 of the disk 7 this being accomplished after t-he reduced end 11 of the arm 8 has been engaged by the spring catch 13 of the plate 12 or when the parts are moved from the position, Fig. 5, to the position, Fig. 6. Thus by holding the roller 55 out of engagement with the disk 7, the brake shoe may be properly actuated when released, the' same being thus free to the action of the spring 8.

In order to limit the up and down swinging movement of the casing 6, a pin 55 is .carried by one of the lugs 4 and is positioned to engage one or the other of the shoulders 53 or 53 of the casing 6, as clearly shown in Fig. 3, thus retaining the casing so that the same will not be permitted to fall upon the record R- when in lower posi'Y tion and limiting the upward movement so that the casing will lean outwardly beyond the perpendicular line and thus be heldy against falling toward the record.

From the foregoingdescription, taken in connection with the drawings it is evident that the present attachment may be attached to any form of disk sound reproducing machine, and that it carries all of the mechanism for stopping the record vR and its platform 3 at any desired position, such point of stoppage being governed by the projection of the rubber stop a relatively to the stylus S, and that also although the same has been shown as being capable of a movement vertically to and from the record R2 y YVhen assembling the presentattachment,

the removable sleeve 60 is employed to t upon the upper porting shaft 2', the same having its upper end so positioned as to register with the aperture 61 of the casing 6, and thus support the casing at the proper elevation above the record carrying platform 3 during thc securing of the casting 4 to the baseor casing 1 of the machine. After the same has been properly attached,the sleeve 60 is removed andthe device is ready to be operated'.
